What Makes PCB Manufacturing So Precise? -
Miracle Electronics

• PCB assemblies are so dense, so complicated,
  filled with so many tiny elements connected
  together, yet so precise! Have you ever wondered
  how something so tiny and complicated can be so
  precise? One of the major reasons for the
  precision is the latest technology used in
  manufacturing PCBs today. While earlier, PCB
  making was a manual process, over the years, the
  PCB manufacturing process has significantly
  changed, thanks to the latest technological
  innovations that have allowed PCB manufacturers
  to innovate accurately and skilfully. Heres how

is made
Pre-manufacturing Planning Before a PCB
prototype is begun for manufacturing, there is a
lot of planning done, considering countless
aspects. First and foremost, the PCB
manufacturer will look over the design and
Gerber files. Then, step-by-step instructions
will be laid out for

fabrication, which will be reviewed by an
engineer, who will then convert these plans into
a data format that will help engineer the board.
Any issues will also be checked for with
formatting or cleaning up. Based on this data,
the final board will be created. Manufacturing St
ep 1 Plotting Once inspected and finalized, a
panel array is then chosen for the best fit,
after which photo plotting begins. This is the
first step of the production process. A laser is
used to plot the patterns, silk screens, and
other primary images that are required on the
PCB. Step 2 Lamination In the case of
multi-layered PCBs, the multiple layers need to
be fused together, which can be attained with
the help of lamination, that is done using heat
and pressure. Step 3 Drilling Once heat and
pressure laminates the layers together, expert
drilling systems are used, programmed to drill
holes into the board, accurately and precisely.
This drilling program ensures that there is no
human error while manufacturing the PCB. Step 4
Copper Deposition and Plating The copper layer
of the PCB, which is deposited through
electrolysis, is an important part of the PCB,
the conductive property essential to the
functionality of the PCB prototype. PCBs
generally become conductive after electroplating,
which is where the copper is plated via a
plating bath. These copper tracks prove

to be conductive tracks that connect two points
within the circuit board. Post-manufacturing
Testing After the prototype is built, it is
thoroughly tested in every way to identify any
mistakes or flaws that may lead to errors or
unexpected end results. Identifying these
mistakes in the prototype can help correct them
right there so that the rest of the manufactured
products are not flawed, thus saving on costs and
time. Once the prototype is confirmed to be
perfect, the remaining lot is manufactured. You
can see how the latest technologies used bring
such precision to PCBs. For such a precise and
accurate PCB assembly from India, you can get in
